Abstract
This tyre (14) is of the semi-hollow type for agricultural machinery, notably for a machine comprising a roller provided with a series of tyres mounted on a horizontal tube (12). Each tyre comprises a central sleeve (26) and at least one tread portion with a dome shaped profile comprising a tread (24) connected to the sleeve (26) by two sidewalls (28, 30) so as to define a hollow annular space (32) of reduced cross section relative to the cross section of the dome shaped profile. It further comprises a plurality of peripheral grippers (34) formed to project from the tread (24) and distributed in the circumferential direction on the top of the dome shaped profile. Alternatively, the tyre may be fitted to an individual wheel.
